Consider the following script:

<?php
echo strtotime("january 1, 1901");
?>

What will be the output of the above PHP script if the older versions of glibc are present in the operating system?

14345

-1

12365

0

Explanation:In any operating system where older versions of glibc are present, the strtotime() function will not be able to identify dates prior to the UNIX period midnight UTC on January 1, 1970. Hence, the output of the script will be -1.
